JOHN BERRY, OF SPRINGFIELD, MASSACHUSETTS, ASSIGNOR TO THE NATIONAL NEEDLE COMPANY, OF SAME PLACE.

NEEDLE-GROOVING MACHINE.

. SPECIFICATION forming part of Letters Patent No. 307,001, dated October 21, 1884.

Application filed March 23, 1833. (No inodehi' 7 To all whom it may concern.-

Be it known that I, J OHN BERRY, a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in NeedleGrooving Machines, of which the following is a specification.

This invention relates to improvements in machines for grooving needles, the object being to provide improved mechanism for operating the transverse cam-shaft, which in such machines is located above the sliding bed thereof, whereby the usual hand-crank on said shaft is dispensed with, and a steadier and more exact intermittent rotary motion is imparted to said shaft, whereby the cutter-shafts and feed-screw nut, which derive certain of their movements from said shaft, are caused to be actuated with greater precision.

Prior to my invention the cutters have been moved laterally up against a needle to groove the same, and a shaft with cams thereon has been used to act upon the sliding cutter-rests, and this shaft has been provided with a segment having a handle, whereby it may be brought into gear with a pinion for feeding the cutters against the needle.

My invention consists in providing the shaft controlling the cutter-rests with peculiar cams and with a broken gear-wheel, whereby a more exact intermittent motion is given to the shaft, and in the peculiar lever connected to the bed of the machine, and provided with arms for engaging with said broken gear-wheel for starting the machine and forbringing itinto proper position for ire-engagement with the driving gear-wheel, all as more particularly pointed out hereinafter.

In the drawings forming part of this specification, Figures I and II are side elevations, and Fig. III is, an end elevation, of a needlegrooving machine embodying my improve ments. Fig. IV is an end elevation of the cross-head and cutter-shaft heads, showing the transverse cam-shaft in section.

In the drawings, A is the frame of the machine. D is the sliding bed. F F are crosshead supports. H is the cross-head. K are cutter-shaft supports on head H. 5 is the transverse cam-shaft. E is a can1-wheel on one end of shaft 5, and 10 is a cam-wheel on arms on wheel E.

the opposite end thereof. .a' is a vertical lever pivoted to the end of a stud, 7, on frame A. a is a hand-lever secured to lever a and having an arm, a, thereon. t and t are short I) is a stud 011 the bed D. c is a stud-block, to which is connected the rod 0", and the latter is pivot-ally connected withlevera". fc (Z are driving-pulleys. eand 3 are driving-bands. I)" is a feed-screw gear. 0* is a pinion. h is a broken gear-wheel on one end of shaft 5. 7L is a driving-gear. 9 is a cam on the inner face of the cam-wheel l0. 12 is a cam-pin. Sis a cam-hook. 6 is a campin. 2 2 indicate groove-cutters, and at the needle. b is the feed-screw.

The above-mentioned transverse shaft 5 in this machine (looking at the front elevation) has secured to its end at the left the cam-wheel E, and to its opposite end, between the gear h and the cross-head H, the cam-wheel 10. A halfelliptic spring, (1, between the slides K, forces the slides apart and the pins 6 and 12 against their cams. E is, in the usual manner, provided with a cam-like lug, 20, (shown in Fig. III,) to strike the end of the cam-pin 6, which. is rigidly secured to slide K, when said lug comes before the end of pin 6, and by acting against said pin, when wheel E revolves, to cause the slide K to move inward for the well-known purpose of forcing the cutter-shaft and cutter, which it supports, toward the needle 4., and letting the cutter reeede from the needle when the lug passes from under said pin to the position shown in Fig. III. The cutter 2 upon the side next to wheel E makes the short groove in the needle, and therefore such devices as are above described are employed to secure a contact of the cutter with the needle of only short duration, or while the lug moves in contact with the end of pin 6 to the position shown in Fig. III.

The direction in which shaft 5 turns is indicated by the arrow over gear h" in Fig. II.

The aforesaid cam-wheel 10 on shaft 5 is, like the cam c in my Patent No. 259,262, of 1882, provided with a cam on its periphery, which operates the cam-hook 8 and the feedscrew nut of this machine substantially in the same manner as saic cam e operates the The inner face of the cam-wheel cam-hook c and feed-screw in said patent.

Said canrwhccl it) has upon its inner face a cam projection, t), which, when said wheel rotates, is carried under or against the end of pin 12, which, like pin (3, is rigid on slide K, whereby the cutter and its shaft, which are supported by said slide, are moved toward the needle 4t. and said cutter is thereby caused to engage with the needle to cut the long groove therein, and after both the long and the short grooves are cut the cam 9 passes from under the end of said pin, as shown in Fig. III. The said cam-wheel E is provided with the short armse' and *i. The vertical lever a is pivoted to the end of the stud 7 on the side of the frame A, and to lever a is secured, near its pivoted end, the hand-lever a, so that said two lovers swing together, or with a common vibratory motion, on said stud, and the arrangement and relations of wheel E and said levers are such that when lever a is swung upward toward said wheel the end of arm a strikes the arm and rotates said wheel and shaft 5 to a certain extent, and when the free end of lever to is swung against arm 1'" wheel. E and said shaft are returned to the position shown in Fig. II. Through the connection of lever a" with the sliding bed D by the rod 0 box 0, and stud b the aforesaid upward movement of lever (4 causes said bed to be moved back on frame A to bring the needle to a proper position for the cutters (first the long and then. the short groove one) to operate upon it.

The arrangement of the parts herein shown for driving the cutter-shafts and the feed-screw Z) is substantially that shown in my said Pat ent No. 259,262, to which reference may be had, and wherein is shown a crank, r, for

turning the transverse shaft there shown.

As above described, by the rotation of shaft 5 the feed nut is brought into engagement with the feedscrew and the long-groove cutter is made to engage with the needle.

The sudden movement of shaft 5,by a careless operator, by means of a crank, as heretofore practiced, often results in injury to the cutter or to the needle, or both, and may re sult in bringing the feed-nut against the feedscrew out of exact time, and thereby injuring one or both of those parts; but said inconveniences are obviated by the. use of the belowdcscribed improved devices for giving the requisite intermittent rotary movements to said shaft On the side of frame A is hung in proper bearings the gear wheel 7:, provided with a suitable band-groove to receive the band 3, by which it is driven independent of the aforesaid partsof the machine, and on the end of said shaft 5 is fixed the broken gear'h the teeth on which engage with those on gear 71 to give it nearly a revolution.

The parts of the machine in the several figures are shown in the positions to which they are brought after the grooving of a needle is completed.

Figs. I and II show a needle placed in the ordinary clamp on bed .1 preparatory to grooving it.

The operation of my improvements, in conjunction with a needle-grooving machine, is as follows: Thegearh runscontinuously. The Operator seizes the lever a and swings it upward, thereby first swinging the free end of lever a? away from eanruhecl E, and by means of the above described connection, by red c of the said lover a and bed 1.), the latter is made at the same time to slide back, carrying the needle between the cutters. Arm a? on lever a then strikes arm 1 on wheel E, turning the latter, shaft 5, and the broken gear If sutficiently to bring that part of its geared portion nearest to wheel 71, as shown in Figs. I and II, into engagement with the teeth of the latter. \Vheel 'lr, shaft 5, and the cam-wheels ll and 10 now rotate to the extent of the toothed portion of the gear 7)., and leaving the latter stopped wit h its u ntoothed part standing above gear it, instead of opposite and below the latter, as shown in Fig. l'. Tl re above-described rotary movement of gear l1? causes shaft 5 and the cam-wheels thereon to be rotated in like manner. The rotation of wheel 10 carries the face of cam 9 against the end of pin 12, cansing the cutter at the right to be carried against the needle, and the movement of the cam V on the periphery of wheel 10, Fig. 1', under the hook 8, lifts up the latter and the feedscrew nut, as described in said Patent No. 259,262, and brings said nut into engagement with the feed-screw b thereby causing the bed D to move (looking at Fig. II) from left to right, carrying the needle along, while said cutter forms a long groove on one side of it. \Vhile cam J is acting on pin 12, as just described, wheel ll rotates before the end ol.

pin (.5, and by the time wheel 713- comes to a stop the cam-socket in said wheel is brought around opposite the end of said pin, and the latter drops into said socket, where it rests, while said long groove is being nearly completed. \Vhen the gear hf comes to a stop, as above described, the pin 12 bearing against the thick part of cam 9, just back of its end, pin 12 occupying said position, and pin is being in the position shown in Fig. 11]., at the same time, and until that part of the needle in which the short groove is to be out comes opposite to the cutter at the left. By this time the movement of bed 1) has brought the end of lever (6 against arm 6'' on wheel E, rotating the latter, shaft 5, and the gear h sufficiently to carry its untoothed portion before gear h to the position shown in Fig. l', but not to engage it therewith, and at the same time so turning wheel E as to cause the camlug w to act on pin (a, and by the latter to give the said short groovecutter a contact with the side of the needle for an instant, and mean while turning wheel 10 to carry cam 9 from opposite pin, 12, and the cam on wheel 10 from under hook 8, so that simultaneously the lat ter drops, carrying the feed-screw nut away from the feed-screw, stopping bed 1) and pins 6 and 12, and thc canrwhcels E and 10 are brought to the positions shown in Figs. 11 and III, and the grooved needle may now be re moved and another needle-blank be secured to the bed and said operations be repeated.

. \Vhat I claim as my invention is- 1. The combination, with the bed D and the shaft 5, of the cam-Wheel E, having the arms 1' i thereon, the rode", the lever a", and hand-lever a, having arm a thereon, substantially as set forth.

2. In combination, bed 1), the cam-shaft 5, the driving-gear h, and broken gear if, and the mechanism, substantially as described, for

rotating gear h to engage it with said gear 15 71 to start the machine and to bring said gear 3. In combination, the bed D, gears h and 20 If, .shaft 5, the ca1n-wheel E, lever a connected with said bed, and lever a, having arm a thereon, and. connected to said lever a", sub stantially as set forth.
